Pizza is an oven-baked flat bread generally topped with tomato sauce and cheese. It is commonly supplemented with a selection of meats, vegetables and condiments. The term first appeared in 997 AD, "in a Latin text from the southern Italian town of Gaeta",[1] in Lazio, Central Italy. The modern pizza was invented in Naples, Italy, and the dish and its variants have since become popular in many areas of the world.[2] In 2009, upon Italy's request, Neapolitan pizza was safeguarded in the European Union as a Traditional Speciality Guaranteed dish.[3][4] Pizza is prepared fresh, frozen and in portioned slices or pieces, and various types of ovens are used to cook pizzas. Many varieties exist, and several similar dishes are prepared from ingredients commonly used in pizza preparation, such as calzone and stromboli.

Etymology

The origin of the word pizza is uncertain. The term "pizza" first appeared "in a Latin text from the southern Italian town of Gaeta in 997 AD, which states that a tenant of certain property is to give the bishop of Gaeta duodecim pizze ("twelve pizzas") every Christmas Day, and another twelve every Easter Sunday".[5][1]

Suggested etymologies include:

The Ancient Greek word πικτή (pikte), "fermented pastry", which in Latin became "picta", and Late Latinpitta > pizza. Compare Greek pita bread and the Apulia and Calabrian pitta.[6]

The Italian word pizzicare meaning "to pluck", which refers to pizza being plucked quickly from the oven (pizzicare was derived from an older Italian word pizzo meaning "point").[10]

The Old High German word bizzo or pizzo meaning "mouthful" (related to the English words "bit" and "bite"), which was brought to Italy in the middle of the 6th century AD by the invading Lombards.[1][11]

Modern pizza evolved from similar flatbread dishes in Naples, Italy in the 18th or early 19th century.[13] Prior to that time, flatbread was often topped with ingredients such as garlic, salt, lard, cheese, and basil. It is uncertain when tomatoes were first added and there are many conflicting claims.[13]

A popular contemporary legend holds that the archetypal pizza, Pizza Margherita, was invented in 1889, when the Royal Palace of Capodimonte commissioned the Neapolitan pizzaiolo (pizza maker) Raffaele Esposito to create a pizza in honor of the visiting Queen Margherita. Of the three different pizzas he created, the Queen strongly preferred a pie swathed in the colors of the Italian flag: red (tomato), green (basil), and white (mozzarella). Supposedly, this kind of pizza was then named after the Queen as "Pizza Margherita",[14] although recent research casts doubt on this legend.[15]

Pizza was brought to the United States with Italian immigrants in the late nineteenth century;[16] and first appeared in areas where Italian immigrants concentrated. The country's first pizzeria, Lombardi's, opened in 1905.[17] Following World War II, veterans returning from the Italian Campaign after being introduced to Italy's native cuisine proved a ready market for pizza in particular.[18] Since then pizza consumption has exploded in the U.S.[19]pizza chains such as Domino's, Pizza Hut, and Papa John's, pies from take and bake pizzerias and chilled and frozen from supermarkets, make pizza readily available nationwide. It is so ubiquitous, thirteen percent of the U.S. population consumes pizza on any given day.[20]

Preparation

Pizza is prepared fresh, frozen, and as portion-size slices or pieces. Methods have been developed to overcome challenges such as preventing the sauce from combining with the dough and producing a crust that can be frozen and reheated without becoming rigid. There are frozen pizzas with raw ingredients and self-rising crusts.

Another form of uncooked pizza is available from take and bake pizzerias. This pizza is assembled in the store, then sold to customers to bake in their own ovens. Some grocery stores sell fresh dough along with sauce and basic ingredients, to complete at home before baking in an oven.

Cooking

In restaurants, pizza can be baked in an oven with stone bricks above the heat source, an electric deck oven, a conveyor belt oven or, in the case of more expensive restaurants, a wood- or coal-fired brick oven. On deck ovens, pizza can be slid into the oven on a long paddle, called a peel, and baked directly on the hot bricks or baked on a screen (a round metal grate, typically aluminum). Prior to use, a peel may be sprinkled with cornmeal to allow pizza to easily slide onto and off of it.[21] When made at home, it can be baked on a pizza stone in a regular oven to reproduce the effect of a brick oven. Another option is grilled pizza, in which the crust is baked directly on a barbecue grill. Greek pizza, like Chicago-style pizza, is baked in a pan rather than directly on the bricks of the pizza oven.

Crust

The bottom of the pizza, called the "crust", may vary widely according to style—thin as in a typical hand-tossed New York-style, or thick as in a deep dish Chicago-style. It is traditionally plain, but may also be seasoned with garlic or herbs, or stuffed with cheese. The outer edge of the pizza is sometimes referred to as the cornicione.[22] Often pizza dough contains sugar, both to help its yeast rise and enhance browning of the crust.[23]

Less expensive processed cheeses have been developed for mass-market pizzas to produce desirable qualities like browning, melting, stretchiness, consistent fat and moisture content, and stable shelflife. This quest to create the ideal and economical pizza cheese has involved many studies and experiments analyzing the impact of vegetable oil, manufacturing and culture processes, denatured whey proteins and other changes in manufacture. In 1997 it was estimated that annual production of pizza cheese was 2,000,000,000 pounds (910,000,000 kg) in the U.S. and 200,000,000 pounds (91,000,000 kg) in Europe.[25]

Another popular Italian style is Sicilian, a thick-crust or deep-dish pizza originating in the 17th century in Sicily. Derived from the sicilian Sfincione,[27][28] is essentially focaccia with toppings. Until the 1860s, Sfincione was the type of pizza usually consumed in Sicily, especially on the western portion of the island.[29]

Additional Italian styles include pizza capricciosa, which is prepared with mozzarella cheese, baked ham, mushroom, artichoke and tomato,[30] and pizza pugliese with tomato, mozzarella and onion.[31]

There are several instances of more expensive pizzas, such as the USD $4,200 “Pizza Royale 007" at Haggis restaurant in Glasgow, Scotland, which has caviar, lobster and is topped with 24-carat gold dust, and the USD $1,000 caviar pizza made by Nino's Bellissima pizzeria in New York City, New York.[35][36] However, these are not officially recognized by Guinness World Records. Additionally, a pizza was made by the restaurateur Domenico Crolla that included toppings such as sunblush-tomato sauce, Scottishsmoked salmon, medallions of venison, edible gold, lobster marinated in the finest cognac and champagne-soaked caviar. The pizza was auctioned for charity in 2007, raising £2,150.[37]

Health issues

Some mass-produced pizzas by fast food chains have been criticized as having an unhealthy balance of ingredients. Pizza can be high in salt, fat and calories. The USDA reports an average sodium content of 5101 mg per 14" pizza in fast food chains.[38] There are concerns about negative health effects.[39] Food chains have come under criticism at various times for the high salt content of some of their meals.[40]

Frequent pizza eaters in Italy have been found to have a relatively low incidence of cardiovascular disease[41] and digestive tract cancers[42] relative to infrequent pizza eaters, although the nature of the correlation between pizza and such perceived benefits is unclear. Pizza consumption in Italy might only indicate adherence to traditional Mediterranean dietary patterns, which have been shown to have various health benefits.[42]

Some attribute the apparent health benefits of pizza to the lycopene content in pizza sauce,[43] which research indicates likely plays a role in protecting against cardiovascular disease and various cancers.[44]

National Pizza Month

National Pizza Month is an observance that occurs for the month of October every year in the United States and some areas of Canada.[45][46][47][48] This observance began in October 1984, and was created by Gerry Durnell, the publisher of Pizza Today magazine.[48] During this time, some people observe National Pizza Month by consuming various types of pizzas or pizza slices, or going to various pizzerias.[45]
